Description

Technical Field

[0001] The utility model relates to the field of reducer equipment, in particular to a high-precision reducer. Background Art

[0002] A high-precision reducer is a reduction device specially designed for precision transmission, with extremely high transmission accuracy and low backlash characteristics. This type of reducer is widely used in aerospace, robotics, precision machine tools, semiconductor manufacturing, medical equipment and other fields that require high-precision motion control and stable transmission. Its main function is to reduce the speed of the input shaft through various transmission methods such as gears, worm gears or planetary gears, and increase the torque of the output shaft accordingly to meet the speed and torque requirements of different mechanical equipment.

[0003] The high-precision reducer is basically composed of a reducer and an upper cover. The upper cover is fixed to the reducer by multiple screws. The upper cover protects the transmission structures such as gears, worms or planetary gears inside the reducer to ensure the normal operation of the internal structure of the reducer. When the high-precision reducer has problems such as increased noise, excessive temperature rise, decreased transmission efficiency, and reduced output accuracy after long-term operation or encountering abnormal working conditions, the staff needs to use the screws to remove them before they can remove the upper cover and maintain the internal structure of the reducer. When removing, the staff needs to use tools to remove multiple screws in turn. In this case, the disassembly process of the reducer and the upper cover is more cumbersome, which reduces the maintenance efficiency of the staff to a certain extent. Utility Model Content
